Monolithic Linear IC

LA8580W

Compander + I/O Switching Telephone Audio

Signal-Processing IC

• Built-in electronic volume control (about 2 dB per step

over 15 steps) and extensive set of level switching

circuits allow this IC to easily switch signals with a wide

range of levels.

• A compander circuit, which provides noise reduction

during communication, is built in. This circuit can also

be used for noise suppression and improved audio

quality in wireless communication systems.

• Built-in splatter filter (fifth order Butterworth filter with

settable center frequency) for reduced parts counts.

Overview

The LA8580W is an I/O switching audio signal-

processing IC for low-power cordless telephone base sets.

It also supports personal fax machines for the Japanese

domestic market. It integrates an extensive set of

functions, including a compander, a crosspoint switch for

I/O switching, an electronic volume control, and level

switching, ALC, VOX, and filter circuits.

Applications

Low-power cordless telephone base sets and Japanese

market home fax machines.

[LA8580W]

12.0

10.0

• Audio level switching (ATT) for the telephone circuit

system, the handset system, both DSP systems, the

doorphone system, and the microphone system

• Dedicated ring-tone input pin (OSC-IN), ring-tone level

switching (OSC-ATT), ring-tone muting (OSC-SW)

• ALC amplifier, audio level detection (VOX),

operational amplifiers for the DSP I/O filters.

• Compressor, limiter (IDC), compressor system muting,

splatter filter.

• Expander, receive system input filter amplifier, and

expander system muting

• Receive system data waveform shaping (with threshold

follower on/off function)

• Serial interface (8-bit serial data input)

SANYO: SQFP64

Features

• Includes a 10 input system/9 output system crosspoint

switch that supports mixing. Systems that provide

flexible and complex switching of signal paths can be

implemented easily.

Any and all SANYO products described or contained herein do not have specifications that can handle

applications that require extremely high levels of reliability, such as life-support systems, aircraft’s

control systems, or other applications whose failure can be reasonably expected to result in serious

physical and/or material damage. Consult with your SANYO representative nearest you before using

any SANYO products described or contained herein in such applications.

SANYO assumes no responsibility for equipment failures that result from using products at values that

exceed, even momentarily, rated values (such as maximum ratings, operating condition ranges, or other

parameters) listed in products specifications of any and all SANYO products described or contained

herein.
